Fifth, the anti-theft door is open outside and insideHow to choose?
1. Choose according to your security needs.
If we live in a less secure area, we may be more inclined to choose an outward door to improve burglar resistance. However, if you consider that there are elderly people and children at home, and you need to escape quickly in an emergency, you may prefer to open the door inward.
2. Choose according to the space situation.
If the entrance of our residence is narrow, or there is a public walkway outside the door, an inside door may be a more suitable option to avoid obstructing the passage of the aisle. Conversely, if there is a large space outside the door, or if it is a private area, the outside door can make full use of the space.
3. Personal habits and preferences.
Some users may choose a specific opening method due to personal habits or preferences for the direction of the door. For example, users who are used to opening a door right-hand may be inclined to choose a door opening method that suits their habits.
The choice of security doors is not static, and there are pros and cons to opening both outside and inside. When choosing, users should comprehensively consider the needs of family members, living environment, security needs and other factors to make the most suitable choice for themselves. At the same time, no matter which opening method you choose, choosing a high-quality and reliable lock security door brand is the fundamental way to ensure home security.
